Manufacturer's Description

The key to many of the virtues of Hydro Flask's zen lies in our patent pending, stainless steel, double wall insulated construction. By leaving a vacuum void between the interior and exterior walls of the bottles, liquids within are insulated from the elements without - hot or cold. Simple and extremely effective. Hot liquids stay steamy for 12 hours or more -even buried deep in glacial snow- while cold liquids stay refreshingly cool for at least 24 hours, long after the trail turns hot and dusty.

Hydro Flask began with a challenge: to create a reusable water bottle that truly performs in any environment. It had to keep hot liquids hot and cold liquids cold. It had to be BPA-free, lightweight, durable, sweat-proof, freeze-proof, recyclable, and come with an unconditional lifetime warranty. Hydro Flask met the challenge! The Hydroflask 24 oz Narrow Mouth bottle is made from 18/8 stainless steel with patent pending double-wall vacuum insulation that ensures the temperature of the liquid inside never mingles with the temperature of the environment outside. The best part is that this is a two-way street; whether you've got hot or chilled liquids inside of your Hydro Flask, the internal temperature won't affect the temperature of the container in your hand. That means no blistered fingers with your daily cup of coffee and no troublesome sweat rings-from your bottle of ice water. Your hots will stay hot for 12 hours, and your colds will stay cold for 24.Patented Narrow MouthDouble Wall Vacuum InsulatedKeeps Hot 12 HoursKeeps Cold 24 HoursBPA-Free18/8 Stainless SteelSignature Matte FinishLifetime WarrantyMade of 18/8 stainless steelMouth Width: 1.44"Size: H 11.5" (with cap) / Diameter: 2.87"Weight: 11.9 oz
